[MCL-7733] Game won't start after clicking on "Start" trough the launcher

Since we're so many to get a bug like that and you can't do "anything" cause none gives you enough material to works with.

I give you 2 files.
And don't tel me isn't enough to find something.
I bought the game to play with some friends, and i can't. That's sad, since it's a known issue...

[EDIT]: Tried with Razer Synaspe/Bitdefender/and all software known to inrefer with Minecraft. Got the same issue "Game doesn't work, sorry for the inconveniance...."
